Islamic Inheritance (Faraid): A Complete Scholarly Overview

The science of Faraid — the Islamic law of inheritance — is one of the most rigorously systematised disciplines in the Sharia. The Prophet Muhammad — peace and blessings be upon him — is reported to have said: “Learn the laws of inheritance and teach them to the people, for they are half of all knowledge.” (Ibn Majah, Tirmidhi). The Companion ‘Abdullah ibn ‘Abbas is reported to have said that the science of inheritance is the first knowledge to be lifted from this ummah. These narrations, although chains vary in strength, capture the elevated status the early community gave to this discipline. A Muslim who dies leaving wealth behind leaves behind also a divine set of instructions about how that wealth must move forward; Faraid is the science of carrying out those instructions faithfully.

This overview is written for the educated Muslim reader — the parent planning an estate, the professional advising a family, the student beginning a serious study of fiqh. We will trace Faraid from its Quranic roots, walk through the four-step distribution sequence that classical jurists established, examine the two principal categories of heirs (the fixed-share heirs and the residuaries), and conclude with the doctrine of hajb (exclusion) and a fully worked numerical example. Citations are drawn from the four Sunni schools of jurisprudence, classical compendia such as Ibn Qudamah’s al-Mughni, al-Marghinani’s al-Hidayah, al-Nawawi’s al-Majmu‘, and Malik’s al-Muwatta’, as well as contemporary bodies including AAOIFI, the International Islamic Fiqh Academy, and the European Council for Fatwa and Research.

1. The Quranic Foundations of Faraid

The substantive law of inheritance in Islam is laid down primarily in Surah an-Nisa (chapter 4) of the Qur’an. Two passages are central: verses 11–12, which fix the shares of children, parents, and spouses; and verse 176, which addresses the inheritance of siblings when the deceased leaves no descendants. These verses are not abstract commands; they prescribe specific fractions and conditions, and they were understood by the Companions as directly actionable law.

Allah the Almighty says:

“Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two-thirds of what he left. And if there is only one, for her is half. And for his parents, to each one of them is a sixth of what he left, if he has a child. But if he has no child and the parents [alone] inherit from him, then for his mother is one-third. And if he has brothers [and/or sisters], for his mother is a sixth, after any bequest he [may have] made or debt. Your parents and your children — you do not know which of them are nearest to you in benefit. [These shares are] an obligation [imposed] by Allah. Indeed, Allah is ever Knowing and Wise. And for you is half of what your wives leave if they have no child. But if they have a child, for you is one-fourth of what they leave, after any bequest they [may have] made or debt. And for them is one-fourth of what you leave, if you have no child. But if you have a child, for them is one-eighth of what you leave, after any bequest you [may have] made or debt…” (Qur’an 4:11–12)

And verse 176:

“They request from you a [legal] ruling. Say, ‘Allah gives you a ruling concerning one having neither descendants nor ascendants [al-kalalah]: If a man dies, leaving no child but only a sister, she will have half of what he left. And he inherits from her [if she dies childless] if she has no child. But if there are two sisters [or more], they will have two-thirds of what he left. If there are both brothers and sisters, the male will have the share of two females. Allah makes clear to you [His law], lest you go astray. And Allah is Knowing of all things.’” (Qur’an 4:176)

These two passages together establish the backbone of Faraid. Imam al-Shafi‘i is reported to have remarked that were it not for these verses, the entire science of inheritance would have remained a matter of custom; Allah instead revealed specific shares, and the jurists’ task became one of systematisation, not legislation. Ibn Qudamah, in the opening of his chapter on inheritance in al-Mughni, states: “The obligation of distributing the estate according to the Book of Allah is established by consensus (ijma’) of the Companions and the generations that followed.” The Qur’anic shares are not negotiable; they are fard — a binding divine prescription.

1.1 The Prophetic Clarifications

The hadith literature supplements the Qur’anic text in two important ways. First, it clarifies the meaning of ambiguous terms. The Prophet — peace and blessings be upon him — is reported to have said: “Give the shares of inheritance to those entitled to them, and what remains [after the fixed shares] goes to the nearest male relative.” (Bukhari and Muslim). This hadith establishes that the residue after the fixed shares passes to the ‘asabah — the male agnate relatives — a principle that became foundational to the Hanafi, Maliki, Shafi‘i, and Hanbali schools alike.

Second, the prophetic practice established that the right to inherit is extinguished by two causes: religious difference (a Muslim does not inherit from a non-Muslim, and vice versa) and enslavement (a slave does not inherit). The hadith “The Muslim does not inherit from the disbeliever, nor the disbeliever from the Muslim” (Bukhari and Muslim) is the textual basis for the first rule. The second rule is grounded in the principle that a slave’s property belongs to his master, and thus there is nothing for him to inherit or to be inherited.

A third cause, widely discussed by the jurists, is homicide: the killer does not inherit from his victim. The Prophet — peace and blessings be upon him — said: “The killer does not inherit.” (Ibn Majah, Tirmidhi). The rationale, as Ibn Qudamah explains, is that one should not benefit from one’s own wrong; allowing a murderer to inherit would create a perverse incentive. The four schools differ on whether this rule applies only to intentional killing or also to accidental homicide; the majority apply it to both, while some Shafi‘i jurists restrict it to intentional murder.

2. The Four-Step Distribution Sequence

Classical jurists established a strict four-step sequence for distributing a deceased Muslim’s estate. The sequence is not a matter of preference or convenience; it is rooted in the Qur’anic text itself, which twice repeats the order “after any bequest he [may have] made or debt” (4:11–12). The sequence is as follows:

2.1 Step One: Funeral Expenses (Takyin al-Mayyit)

The first charge against the estate is the cost of a modest, dignified funeral. Imam al-Marghinani in al-Hidayah specifies that this includes washing the body (ghusl), shrouding it (kafan) in three clean white cloths for a male (or five for a female, according to the majority), transporting it to the place of burial, and the burial itself. The expenses must be reasonable; extravagance in funerals is discouraged by the hadith reported in Muslim: “Hasten the funeral procession.” The cost is taken from the estate before any debts, bequests, or shares are computed.

Notably, if the deceased left no estate, the cost falls upon the relatives who would have been responsible for his maintenance in life; failing that, upon the Muslim community (the bayt al-mal). No Muslim may be denied a dignified burial for want of funds.

2.2 Step Two: Settlement of Debts (Qada’ al-Duyun)

After funeral costs, all outstanding debts of the deceased must be settled in full. This includes:

• Debts owed to human beings (loans, unpaid wages, deferred mahr owed to a wife, unpaid zakat that became due before death).
• Debts owed to Allah that have a human intermediary — such as unpaid zakat, expiatory obligations (kaffarat), and unperformed Hajj that was obligatory.
• Tax liabilities owed to a legitimate public authority.

The Prophet — peace and blessings be upon him — refused to lead the funeral prayer for a deceased Companion who had died leaving unpaid debt, until Abu Qatadah undertook to pay it on his behalf (Bukhari). This established the gravity of debt in the eyes of the Sharia. Ibn Abidin, in Radd al-Muhtar, notes that secured debts (those with collateral) are paid from the specific collateral, while unsecured debts are paid pro rata from the remaining estate if the assets are insufficient to satisfy all creditors in full.

A matter of contemporary importance is the modern mortgage. If a Muslim dies while still owing instalments on a Sharia-compliant home financing (murabaha, musharakah mutanaqisah, or diminishing partnership), the outstanding balance is a debt that must be paid before inheritance distribution. The same applies to a conventional mortgage, although the contractual sin is borne by the deceased and the family should seek repentance and, where possible, restructuring of the loan. The European Council for Fatwa and Research (ECFR) has addressed this scenario in several resolutions, urging Muslims in the West to plan ahead so that their families are not left with a contested debt burden.

2.3 Step Three: Execution of the Bequest (Tanfith al-Wasiyyah)

After debts, up to one-third of the remaining estate may be distributed according to the deceased’s written or oral bequest (wasiyyah). The one-third limit is established by the hadith of Sa‘d ibn Abi Waqqas, who sought the Prophet’s permission to bequeath his entire estate. The Prophet replied: “One-third, and one-third is much. It is better for you to leave your heirs rich than to leave them poor, begging from people.” (Bukhari and Muslim).

Three principles govern the wasiyyah:

1. The one-third ceiling — anything beyond this requires the unanimous consent of the adult heirs after the death; absent that consent, the excess is void.
2. No bequest to a legal heir — the Prophet said: “Allah has given every rightful person his right, so there is no bequest for an heir.” (Abu Dawud, Tirmidhi). A parent cannot bequeath extra to one of his children beyond their Faraid share, unless all other adult heirs consent after the death.
3. The wasiyyah takes effect after debts and funeral expenses — the Qur’anic phrasing is unambiguous on this sequence.

If a Muslim dies leaving a legal heir in financial distress, the wasiyyah may be used to direct up to one-third of the estate to that heir through the mechanism of tanfith with the posthumous consent of the other heirs. Alternatively, the deceased may gift wealth during life to a favoured heir — a route that the Hanafi school permits, though Imam Ahmad ibn Hanbal is reported to have disliked gifts to one child over others without a valid reason.

2.4 Step Four: Distribution Among Heirs (Qismat al-Turath)

Only after the first three steps are completed does the remaining estate pass to the heirs according to the rules of Faraid. The order within this distribution itself follows a strict hierarchy: the fixed-share heirs are paid first, the residue then passes to the residuaries, and if no residuary exists, the residue returns to the fixed-share heirs (other than the spouse) under the doctrine of radd, which we will address in a separate article. If no heir of any kind exists, the estate escheats to the public treasury (bayt al-mal), to be spent on public welfare.

3. Categories of Heirs: The Fixed-Share Heirs (Ashab al-Furud)

The classical jurists identified ten relationships that give rise to a fixed Quranic share. These are collectively known as asbab al-furud — the causes of the fixed shares — and the individuals inheriting through them are called asbab al-furud al-muqaddarah, or ashab al-furud for short. The fixed shares are six in number: one-half, one-quarter, one-eighth, two-thirds, one-third, and one-sixth (with a seventh share of one-third of the residue appearing in a single case under the Maliki school).

The ten relationships are:

1. Husband — inherits one-half if the wife has no descendants (child, grandchild through a son, etc.), and one-quarter if she does.
2. Wife (or wives) — share one-quarter if the husband has no descendants, and one-eighth if he does. Multiple wives share their portion equally.
3. Father — inherits one-sixth plus the residue if the deceased has a descendant (son, daughter, son’s son, son’s daughter); one-sixth if the deceased has no descendant but has brothers; and the whole estate (as a residuary) if the deceased has neither descendants nor brothers.
4. Mother — inherits one-sixth if the deceased has a descendant or two or more brothers (full, paternal, or maternal); one-third if the deceased has neither; and one-third of the residue under the special case of al-gharrawayn (the parents with the spouse) discussed below.
5. Grandfather (paternal) — inherits in place of the father when the father is absent. His share depends on the presence of siblings, leading to the famous disagreement between the schools (the “grandfather with siblings” problem).
6. Grandmother (paternal or maternal) — inherits one-sixth, shared between them if both exist, when the mother is absent.
7. Daughter — inherits one-half if alone, and two-thirds if two or more, when there is no son. If there is a son, she becomes a residuary with him at a 2:1 ratio.
8. Son’s daughter (or lower) — inherits one-half if alone, two-thirds if two or more, and one-sixth as a corrective share when she coexists with a single daughter of the deceased.
9. Full sister — inherits one-half if alone, two-thirds if two or more, when there is no male sibling of equivalent degree and no descendants or father/grandfather.
10. Paternal sister — inherits one-half if alone, two-thirds if two or more, and one-sixth as a corrective share when she coexists with a single full sister.
11. Maternal sibling (uterine brother or sister) — inherits one-sixth if alone, and one-third if two or more, shared equally between male and female.

This enumeration is the cornerstone of the discipline. The Hanafi scholar al-Sijistani famously codified the heirs in a mnemonic verse still memorised by students: “The shares are six, the heirs are ten” — a reminder that the entire system is built on ten relationships interacting across six possible fractions.

4. The Residuaries (Al-‘Asabah)

The fixed shares rarely exhaust the estate exactly. When the fixed shares leave a residue, that residue passes to the ‘asabah — the residuary heirs. The Prophet’s hadith “Give the shares to those entitled to them, and what remains goes to the nearest male relative” establishes this principle. The residuaries are classified into three categories:

4.1 Residuary by Himself (Asabah bi-Nafsihi)

These are male agnates who inherit the entire residue, or the whole estate if no fixed-share heirs exist. They are arranged in a strict order of priority:

1. The son, then the son’s son (descending)
2. The father, then the paternal grandfather (ascending)
3. The full brother, then the paternal brother
4. The son of the full brother, then the son of the paternal brother
5. The full paternal uncle, then the paternal uncle’s son, and so on through the agnatic line

Within each tier, the closer excludes the more remote; within the same tier, the descendant of a closer agnate excludes the descendant of a more remote agnate. Thus a living son excludes a grandson; a living full brother excludes a nephew; a living paternal uncle excludes a cousin.

4.2 Residuary by Another (Asabah ma’a Ghayrihi)

These are females who become residuaries when they coexist with a male of equivalent degree. The four principal cases are:

• Daughter with son — the daughter who would have taken a fixed share of one-half or two-thirds now takes residually with her brother at a 2:1 ratio.
• Son’s daughter with son’s son — same principle.
• Full sister with full brother — same principle.
• Paternal sister with paternal brother — same principle.

In each case, the male takes double the female’s share — a reflection of the Quranic principle stated in Surah an-Nisa (4:11): “for the male, what is equal to the share of two females.” We treat the underlying rationale in a dedicated article; for now we note only that the rule applies in the residuary context identically to the fixed-share context.

4.3 Residuary with Another (Asabah ma‘a Ghayrihi in Another Sense — Tawsiyah)

The third category, recognised by the Hanafi school, includes the full sister and the paternal sister when they coexist with the daughter or son’s daughter. The full sister is “made residuary” with the daughter, taking what remains after the daughter’s fixed share. Imam Abu Hanifa reasoned that just as the daughter shifts from a fixed share to residuary status when a son appears, so too the full sister shifts when a daughter appears — because both are female agnates of equivalent degree. The other schools disagree and give the sister her fixed share in such cases. This is one of the famous points of divergence between Abu Hanifa and his two prominent students, on one side, and Imam Malik, al-Shafi‘i, and Ahmad on the other.

5. The Doctrine of Hajb (Exclusion)

The number of heirs who actually inherit in any given case is rarely the full ten. Most potential heirs are excluded by the presence of a closer relative. The mechanism by which a nearer heir blocks a more remote one is called hajb. Classical jurists distinguish two forms:

5.1 Total Exclusion (Hajb Hirman)

In total exclusion, the blocked heir receives nothing at all. Examples include:

• The son excludes the son’s son — the descendant who is closer in degree blocks the more remote descendant.
• The father excludes the paternal grandfather — an ascendant closer in degree blocks the more remote ascendant.
• The full brother excludes the paternal brother and the son of the full brother — the closer agnate blocks both the half-blood agnate and the nephew.
• The son (or daughter, or son’s son) excludes the full brother — any descendant blocks all siblings.
• The father (or paternal grandfather) excludes the full brother — any male ascendant blocks all siblings.
• The son’s daughter is excluded by two or more daughters — because the daughters’ two-thirds share exhausts the available share for female descendants.

The rules of total exclusion are essentially rules of proximity: a nearer agnate blocks a more remote one; a descendant blocks a sibling; an ascendant blocks a sibling in most cases.

5.2 Partial Exclusion (Hajb Nuqsan)

In partial exclusion, the heir’s share is reduced from a larger to a smaller fixed fraction. Two classic examples dominate:

• The husband’s share falls from one-half to one-quarter when the wife has a descendant. The presence of a child reduces his share by half.
• The wife’s share falls from one-quarter to one-eighth when the husband has a descendant.
• The mother’s share falls from one-third to one-sixth when the deceased has a descendant or two or more siblings. This is the famous “umariyyatayn” reduction.
• The full sister’s share falls from one-half (or two-thirds) to a residuary position when she coexists with a daughter (under the Hanafi view).

Ibn Qudamah, in al-Mughni, observes that partial exclusion reflects a delicate balancing: the Qur’an designed the system so that the spouse’s share automatically contracts when the deceased leaves descendants, since the descendants will inherit the bulk and the surviving spouse’s needs are partly secured by the children. The reduction is not arbitrary but reflects an integrated financial ecosystem.

6. A Worked Numerical Example

Consider a Muslim man who dies leaving a wife, one daughter, a father, and a mother. His net estate after funeral expenses, debts, and bequests is £120,000. How is the estate distributed?

Step 1: Identify the fixed-share heirs.

• Wife: one-eighth (because the deceased has a descendant — the daughter). One-eighth of £120,000 = £15,000.
• Mother: one-sixth (because the deceased has a descendant). One-sixth of £120,000 = £20,000.
• Father: one-sixth (because the deceased has a descendant). The father also takes the residue as a residuary. One-sixth = £20,000.
• Daughter: one-half (because she is alone, with no son). One-half of £120,000 = £60,000.

Step 2: Sum the fixed shares. £15,000 + £20,000 + £20,000 + £60,000 = £115,000. The residue is £5,000.

Step 3: Distribute the residue. The father, as the nearest male agnate, takes the residue. The father’s total = £20,000 + £5,000 = £25,000.

Final distribution:

Heir	Share	Amount
Wife	1/8	£15,000
Mother	1/6	£20,000
Father	1/6 + residue	£25,000
Daughter	1/2	£60,000
Total		£120,000

This example illustrates the elegance of the system. The spouse, parents, and daughter each receive their Quranic entitlement; the residue passes to the father as the nearest agnate; the entire estate is accounted for without any waste or arbitrary allocation.

7. Common Misconceptions

Several misconceptions about Faraid circulate in popular discourse, and the responsible Muslim planner should be aware of them.

Misconception 1: “Islam always gives the male double the female.” This is false. The 2:1 ratio applies in the residuary context (son:daughter, brother:sister) and in some fixed-share contexts, but in many cases women inherit equally to or more than men. A mother and father each take one-sixth when the deceased has a child; a maternal brother and sister share one-third equally; a sole daughter takes one-half while a sole son takes the whole estate (which may be more, but the daughter’s share is larger proportionally when only daughters exist). The system is more nuanced than the simple slogan.

Misconception 2: “The wife inherits less because she is a woman.” The wife inherits one-eighth (or one-quarter) not because of her sex but because the system balances her share against the children’s shares and her own maintenance rights. The husband inherits one-quarter (or one-half) not because he is a man but because he bears the legal duty of maintenance (nafaqah) toward his wife and children.

Misconception 3: “Faraid is outdated.” The Quranic shares are divine prescription; the juristic superstructure (hajb, ‘awl, radd) is human interpretation of divine principles. The latter can be and is regularly refined by qualified scholars in response to new social realities; the former cannot. The contemporary bodies — AAOIFI, the International Islamic Fiqh Academy, ECFR — continue to issue guidance applying Faraid to modern asset classes, cross-border estates, and digital wealth.

8. Conclusion

Faraid is a science that combines rigorous mathematical structure with deep ethical vision. It allocates wealth not by the whim of the deceased but by a divine scheme that ensures every close relative receives a defined share, that no one is wholly disinherited (except in cases of moral ineligibility such as homicide or apostasy), and that the family unit is preserved through the generations. The four-step sequence — funeral, debts, bequest, distribution — ensures that the deceased’s moral obligations are settled before his wealth passes onward. The two-tier system of fixed shares and residuaries balances the interests of spouses, parents, children, and siblings in a way no human legislator has rivalled.

The Muslim who learns this science, even at an introductory level, gains not only practical knowledge for his own estate planning but also a deeper appreciation for the coherence and beauty of the Sharia. Faraid is, as the Prophet indicated, half of all knowledge — not because it is half the law in volume, but because it is the law’s concluding application to the life of every Muslim.

Frequently Asked Questions

Q1. Do adopted children inherit under Faraid?
No. Adoption in the modern legal sense does not create a Faraid relationship. The Qur’anic verse (33:4) “He has not made your adopted sons your [true] sons” establishes this rule. However, an adopted child may receive up to one-third of the estate through a wasiyyah, and the deceased may also have gifted assets during life. Many contemporary scholars also encourage formalising care arrangements through a waqf or trust.

Q2. Can a Muslim write a will leaving everything to one child?
Not for the portion covered by Faraid. The Quranic shares are binding. However, the deceased may leave up to one-third by wasiyyah to anyone (including a child, with the posthumous consent of the other heirs), and may make gifts during life. The Hanbali scholar Ibn Qudamah discouraged unequal gifts to children without a valid reason.

Q3. Does a non-Muslim relative inherit from a Muslim?
The majority position, based on the hadith “The Muslim does not inherit from the disbeliever”, is no. However, a Muslim may bequeath up to one-third to a non-Muslim relative through a wasiyyah, and Imam Muhammad ibn al-Hasan al-Shaybani reportedly permitted inheritance between Muslims and non-Muslims on the basis of a shared religion (i.e., a non-Muslim inheriting from a non-Muslim), but not across the religious divide. Some contemporary scholars, notably the ECFR, have allowed a kind of wasiyyah wajibah (obligatory bequest) to non-Muslim relatives, limited to one-third.

Q4. What happens if there are no heirs at all?
If no Quranic or agnatic heir exists, the estate escheats to the bayt al-mal (the public treasury of the Muslim community). In modern states without an Islamic bayt al-mal, contemporary scholars advise directing the estate to Islamic charitable causes that approximate the public welfare function of the bayt al-mal.

Q5. Is it permissible to distribute the estate differently to avoid conflict?
Any deviation from the Faraid shares requires the informed, free, posthumous consent of all adult heirs who would otherwise receive a larger share. If all heirs voluntarily agree to redistribute among themselves after taking their shares, this is permissible as a gift among living persons. But the deceased may not unilaterally override the Faraid shares during life through a will.
